At DataJack, with no contract required, purchase the 5GB DataJack Data Plan for $49.99 per month and get the DataJack USB Modem for free. (The discount should apply automatically via the link; otherwise, apply coupon code "USBFREE".) With free shipping, that's $80 off and tied with last week's mention as the best price we've seen for this plan. (The USB modem itself was $10 more, before the cost of a plan, two weeks ago.) The modem features space for a Secure Digital memory card of up to 32GB and provides 3G connectivity. Deal ends February 29.
